FLUSH-TANK FOR WATER-CLOSET APPARATUS.

To all whom it may concern Be it known that I, WILLIAM U. GRIF- FITI-IS,a citizen of the United States, and a resident of Philadelphia, in thecounty of Philadelphia and State of Pennsylvania, have invented certainnew and useful Improvements in Flush-Tanks for Water- Closet Apparatus,of which the following is a specification. 7

My invention relates to improvements in flush tanks for flushing watercloset hoppers and the like, and it has for. its object tov provide animproved construction of meansfor starting the siphonic action of asiphon situated in the flush tank.

A further object of my invention is to provide a construction which issimple and therefore may be economically manufactured, and one whichalso is efficient and positive in its action.

In the accompanying drawing I have illustrated one form of a convenientembodiment of my invention, but it will be underthe details ofconstruction may be made within the scope of the claim without departingfrom the same.

In the drawing I have shown a water closet apparatus embodying myinvention, the flush tank and a portion of the adjacent mechanism beingshown in-vertical longitudinal section, while the water closet bowl orhopper and other associated mechanism are shown in side elevation.

Referring to the drawing, 1 designates a water closet hopper or bowl and2 a valve mechanism for controlling the flow of water from the source ofsupply through a pipe 3 to the flush tank 4:. The valvemechanism iscontrolled by means of a vertical rod 5 op.- erated by the seat 6 whenthe "latter is depressed. The seat is normally held in raised position,as shown in the drawings, by means of a weighted arm or lever 7, therear end of which is adapted to bear against and raise or lift avertical rod'8 when the seat is depressed downwardly upon the upper edgeof the water closet bowl. The rod 8 is guided in its vertical movementsin a well known manner. The upper end of the rod 8 projects into achamber 9 formed at the lower end of the long leg of a1 siphon 10. Thesiphon is situated in the flush tank 4 in the usual and known manner.

11v designates a chamber or receptacle which is situated in the chamber9 and is Specification of Letters Patent.

secured in position by means of screws 12,.

one only of which is shown, which engage a flange 13 formed upon thesiphon structure. The screws 12 extend through flanges lL upon the outeredge of the receptacle or chamber .11. The bottom of the receptacle orchamber is provided with an opening 14, while the top is provided withan opening 15; The opening 14 is adapted to be closed lows: Then theseat 6 is depressed, it contacts with the upper end of the rod 5 toposition the valves in the mechanism 2 so as to permit water to flowinto the tank 4; and fill the same. At the same time, the rod 8 is movedupwardly, its upper end contacting with the valve 16 to cause the sameto close theopening 14c. Simultaneously, the opening 15 is opened.Consequently when the water has reached a level in the tank which isabove the plane of the top of the receptacle or chamber 11, water flowsinto the latter through the opening 15 to fill the same. When the seat 6returns to the position illustrated in the drawing, the rod 8 drops downinto the position also illustrated in the said drawing, permitting thevalve 16 to open the opening 14, and simultaneously closing the opening15. The water which has been collected in the receptacle or chamber 11flows out through the opening 14:. The quantity of water in thereceptacle or chamber 11 is suflicient to start siphonic action. Theresult is that the water is dis- Iatented June 8, 1915.
